Unlocking the power of fractal antennas.


 

If you're into antenna experiments, check out this video from Simon (VA7BIX).

Simon makes a good copy of a "fractal antenna" for HF testing.  This unconventional antenna design is widely used in cell phones and some UHF television antennas.

In this instance, Simon's antenna was placed on 10 meters where propagation was poor for testing day.  Simon will investigate his project when propagation improves.

Nonetheless, this antenna design has some promise, so stay tuned for Simon's update.

Unlocking the Power of Fractal Antennas! 🌀📡 | Fact or Fiction? #hf #antenna #hamradio G'day Mates, this fun video is diving into the mysterious world of "Fractals" and the "Hilberts Curve" a series of infinite squares, and in this instance, what does adding 'fractal squares' do to the SWR to an ordinary 6ft piece of 3 inch metal tape? Let's watch and find out - wooohooo. Cheers and beers mates, and see ya on the airwaves soon. ps. the band conditions on 10 meters were poor, so this was just an objective side by side comparison of what cutting the squares did for impedance and resonance.

Building a ZS6BKW antenna from scratch. Post #1559.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BfUbL_4VCww. The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE,  show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands.  Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Antenna for Condo Backyard-Stealth. Post #1542.

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio.  In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort.  Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.
